Abstract
The utility model discloses an anti-freezing anti-explosion pipe joint. The anti-freezing anti-explosion pipe joint is formed by bonding two identical half-joints (1) in bilateral symmetry. Each half-joint (1) comprises an outer sleeve (2) and a buffer tube (3), wherein a connector (4) is integrally formed at one end of the outer sleeve (2) in a casing coupling mode through injection molding, the buffer tube (3) is mounted on the inner wall of the other end of the outer sleeve (2) through a locating groove (5), and a deformation space (6) is formed between the outer sleeve (2) and the buffer tube (3). The anti-freezing anti-explosion pipe joint is simple in structure and convenient to use; the deformation space between the outer sleeves and the buffer tubes has a large elastic deformation range; when pressure exceeds a certain range, deformation is conducted in the deformation space first so as to release the pressure; when the pressure is relieved, the outer sleeves and the buffer tubes restore to the original shapes under the action of compressed air and elasticity of the outer sleeves and the buffer tubes.
Description
Technical field
The utility model belongs to pipeline installing area, is specifically related to anti-frozen burst pipe joint.
Background technique
In daily life, when winter, there's a sudden fall in temperature in many cold areas, if be not incubated in time and often easily produce booster phenomenon, for processing this class problem, need to waste a large amount of manpower and materials, trace it to its cause is because in this confined space of pipeline, when water becomes ice, volumetric expansion causes high pressure, when pressure surpasses the ability to bear of pipeline, has had this pressure release mode of booster only.
Summary of the invention
The purpose of this utility model is: a kind of anti-frozen burst pipe joint is provided, and the Packed space that can produce certain deformation in the cavity of this pipe joint, for the quick increase of compensator or trimmer pressure, avoids booster phenomenon, increases the service life, and reduces maintenance cost.
Technical solution of the present utility model is: this pipe joint is by two symmetrical bonding forming of identical half-section, described half-section comprises outer sleeve and separator tube, at one end of outer sleeve casing coupling formula integrated injection moulding connection mouth, on the inwall of the other end of outer sleeve, through locating slot, separator tube being installed, is deformation space between outer sleeve and separator tube.
When pipe joint internal cause freeze to produce volumetric expansion and forms high pressure, separator tube expands, thereby reduces pressure, avoids pressure to surpass the possibility that pipeline bears the limit; After ice-out, under the air pressure and the flexible effect of separator tube self in deformation space, separator tube progressively recovers normal state.
The utility model is simple in structure, easy to use, between the gentle washing pipe of outer sleeve, is deformation space, and have compared with large elastic deformation scope, when pressure surpasses certain limit, deformation first here discharges presses, after pressure relieving, under pressurized air and self flexible effect, restore to the original state.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 half-section, 2 outer sleeves, 3 separator tubes, 4 connection mouths, 5 locating slots, 6 deformation spaces.
Embodiment
As shown in Figure 1, this pipe joint is by two symmetrical bonding forming of identical half-section 1, described half-section 1 comprises outer sleeve 2 and separator tube 3, at one end of outer sleeve 2 casing coupling formula integrated injection moulding connection mouth 4, on the inwall of the other end of outer sleeve 2, through locating slot 5, separator tubes 3 being installed, is deformation space 6 between outer sleeve 2 and separator tube 3.
When pipe joint internal cause freeze to produce volumetric expansion and forms high pressure, separator tube 3 expands, thereby reduces pressure, avoids pressure to surpass the possibility that pipeline bears the limit; After ice-out, under the flexible effect of the air pressure in deformation space 6 and separator tube 3 self, separator tube 3 progressively recovers normal state.
Claims (1)
